PS:下面看下mysql如何查询当天信息？
原来不是太熟悉SQL查询语句，什么都是用到了再去查去找，还好网络提供给我们很多支持。今天又用到了一个语句，一时间真想不出怎么解决，到网上看了看，感觉就有一个，怎么那么简单啊。需要积累的东西真是太多了。
今天就把我这个简单的问题记录下来吧!算是一个积累：
mysql查询当天的所有信息：
|
1
|
select * from test where year(regdate)=year(now()) and month(regdate)=month(now()) and day(regdate)=day(now())
|
这个有一些繁琐，还有简单的写法：
|
1
|
select * from table where date(regdate) = curdate();
|
date()函数获取日期部分, 扔掉时间部分，然后与当前日期比较即可
